Solving One Step Equations Addition Equations
There are four things that you must remember when solving any equation AND everything must be mathematically correct!
|
Your goal is to get the variable that you are solving for by itself on one side of the equation.
Example: x = _____
To eliminate a term on one side of the equation,
you use the opposite mathematical operation.
Whatever you do to one side of the equation, you MUST do to the other side of the equation. This keeps the equation balanced!
Always check your answer by substituting the value back into the original equation.

Let's take a closer look at the three rules above in an example problem.

If you'd like to see more examples on video, check out the Solving Equations E-course. You'll find not only more step-by-step examples on video, but you'll also find practice problems with step-by-step solutions.
Here we have two more examples of how to solve a one step addition equation! I've even thrown in a few negatives, because that can sometimes
confuse you, especially if you don't remember your
addition integer rules
or your
subtraction integer rules.


Ok... ready for a few practice problems? If you get stuck, go back and follow the example problems again!
